Arrhythmia News and Research

RSS

An arrhythmia is a problem with the speed or rhythm of the heartbeat. During an arrhythmia, the heart can beat too fast, too slow, or with an irregular rhythm. A heartbeat that is too fast is called tachycardia. A heartbeat that is too slow is called bradycardia. Most arrhythmias are harmless, but some can be serious or even life threatening. When the heart rate is too slow, too fast, or irregular, the heart may not be able to pump enough blood to the body. Lack of blood flow can damage the brain, heart, and other organs.

New insights into how viruses disrupt heart function and lead to sudden cardiac deaths

In a potentially game-changing development, scientists with the Fralin Biomedical Research Institute at VTC have revealed a new understanding of sometimes fatal viral infections that affect the heart.

Study shows link between sweetened drinks and higher atrial fibrillation risk

Adults who reported drinking two liters (about 67 ounces) or more of sugar- or artificially sweetened drinks per week had a higher risk of an irregular heart rhythm known as atrial fibrillation compared with adults who drank fewer such beverages, according to new research published today in Circulation: Arrhythmia and Electrophysiology, a peer-reviewed journal of the American Heart Association.

Taking medical cannabis for chronic pain linked to increased risk of arrhythmia

People taking medical cannabis for chronic pain have a slightly increased risk of arrhythmia, according to research published in the European Heart Journal today (Thursday). Arrhythmia is when the heart beats too slowly, too quickly or irregularly. It includes conditions like atrial fibrillation.

Lasting heart concerns in kids post-MIS-C: Study urges ongoing cardiac checks

Researchers evaluated the long-term cardiovascular effects in children after treatment for MIS-C, a condition linked to COVID-19. They found that regardless of initial heart injury, most children displayed persistent cardiac abnormalities, underscoring the importance of ongoing cardiac monitoring post-recovery.

Intensive blood pressure treatment lowers risk of cardiovascular events in high-risk patients

An intensive three-year intervention to lower the top blood pressure number to less than 120 mm Hg was more effective at preventing death, heart attack, stroke and other cardiovascular events in adults at high risk for cardiovascular disease, compared to the standard treatment target of under 140 mm Hg, according to late-breaking science presented today at the American Heart Association's Scientific Sessions 2023.
